Crossley desk-type telephone transmitter, made by Emmot and Blakey, Bradford, West Yorkshire, England, 1879.
Louis John Crossley (1842-1891) was a wealthy carpet manufacturer, but he was also responsible for improving Professor David Edward Hughes' (1831-1900) crude carbon transmitter, eventually taking out a patent for his improvements (patent Number 412 of 1879). Crossley was also acquainted with Walter Emmot and Edwin Blakey, who were attempting to introduce the Bell telephone to the UK, but were struggling to find an effective transmitter. The Crossley instrument was widely used for private wire and early telephone exchanges, and for a few years was the standard telephone used by the Post Office, until it was superseded by the Gower-Bell telephone.
